[Field of the Invention]
The present invention relates to a receiving bracket having a sickle piece receiving mechanism for a sliding door lock and a method for attaching the receiving bracket to a door frame.
[0002]
[Prior art]
Currently, when the sliding door lock is closed, the sickle piece receiver is equipped with both a "no-adjustment means for preventing rattling in the vertical and inclined directions" and "no-adjustment means for dust in the opening direction" of the sliding door. The appearance of metal fittings is desired.
[0003]
The reason for this is that if the toyoke that constitutes the bracket is fixed in the recess of the door frame, the strike must be removed and the position of the sliding box, etc. in the toyoke must be adjusted. Of course, an expert is required to adjust the backlash in this way. In particular, when the technical purpose of the sickle piece receiving mechanism of the sliding door lock bracket is set to "preventing rattling", for example, 3 mm between the strike receiving plate and the front of the sickle lock body. When predetermined dust such as 5 mm is set, it is desired to prevent rattling in the pulling direction as much as possible.
[0004]
[Problems to be solved by the invention]
As described above, the present invention requires the labor of a skilled person to perform “backlash adjustment” and “chile adjustment” in the sickle piece bracket, so that this inconvenience is eliminated. Objective. Therefore, the first purpose is that when the sickle piece is locked when the door is closed, it is not necessary to adjust both the “backlash adjustment” and the “chile adjustment” on the side of the bracket with respect to the sickle piece. It is providing the receiving metal fitting which has an adjustable sickle piece receiving mechanism, and the method of attaching this receiving metal fitting to a door frame. The second object is to reliably prevent backlash even when a predetermined size of dust is set. In this case, it is desirable to precisely prevent backlash. Even within a range where a predetermined dust (for example, a gap of 3 mm or less) is set between the receiving plate of the movable strike and the front of the lock body, the upper and lower engagements correspond to the dust setting when the sliding door is locked. It is an object of the present invention to prevent backlash at all times even when the sliding body is selectively engaged, and this adjustment is not performed.

Therefore, the upper engagement sliding body 105 rises against the spring force of the spring 116 when the upper engagement slide body 105 is guided by the upper guide rod 112 and descends.
[0044]
In the above configuration, the main part of the present invention will be described with reference to FIGS. In the present invention, there are many new creation parts when paying attention to the relationship with the combination of each constituent member. However, in relation to the specific requirements of the present invention, these new matters are not limited to independent claims. Detailed description of the combination of each member will be omitted.
[0045]
5 and 6 show that the case main body 50 has two pieces in the state where the upper and lower engaging sliding bodies, the upper and lower guide rods, the urging spring and the like are incorporated in the case main body 50 and the movable strike 70. The state is shown in which the metal plate 4 is integrally fixed to the mounting plate 85 via the first fixing tool 61 and the receiving metal fitting 4 is mounted in the recess of the door frame 3 via the two second fixing tools 87. .

In this mounted state, the receiving plate 71 outer wall surface 71a of the movable strike 70 of the bracket 4 is energized by the amount set in advance (for example, 5 mm) as compared with the outer wall surface 85a of the mounting plate 85. The spring 90 protrudes due to the spring force.
At this time, since the end surface 76 of the ear-shaped portion 75 of the slide end plate portion 73 is in contact with the inner wall surface of the mounting plate 85, the movable strike 70 does not protrude from the fitting port 88 beyond the set “tilt a”. . When the movable strike 70 pushes the outer wall surface 71a of the receiving plate 71, the movable strike 70 can be retracted into the case body 50 against the spring force of the biasing spring 90 by an amount corresponding to the setting of the dust.
[0047]
Therefore, it is assumed here that the sliding door 1 is closed from the opened state shown in FIG. When the sliding door 1 is closed, the sickle piece 20 comes out of the entrance 9 of the lock body 2 by the power conversion mechanism (for example, the relationship between the rack and the pinion) as shown in FIG. Enter the window 72. The distal end portion 24 of the sickle piece 20 that has entered the receiving metal fitting 4 first hits the receiving portion 95 of the lower engagement sliding body 92. At this time, the lower engagement sliding body 92 is lifted according to the amount of rotation of the sickle piece 20, so that the lower engagement sliding body 92 is guided by the lower guide rod 100 and rises against the spring force of the return spring 102. To do. When the lower engagement sliding body 92 is raised, the continuous meshing teeth 99 are always engaged with the continuous meshing teeth 109 of the upper engagement sliding body 105 regardless of the protruding position of the movable strike 70. (Square piece or sliding door play prevention function: meaning of no play adjustment).
[0048]
Next, when the movable strike 70 is pressed by the front 6 of the lock body 2 and retracted into the case body 50 when the door is closed, the upper engagement sliding body 105 can move to the movable strike 70 via the elongated guide plate 110. Since it is attached to the case body 50, the movable strike 70 is moved back into the case body 50 "by the amount necessary to adjust the dust". At that time, since the upper engagement sliding body 105 is biased by the spring 116, it is guided by the upper guide rod 112 and slides downward. As a result, the positions of the meshing teeth 99 of the lower engagement sliding body 92 and the meshed teeth of the upper engagement sliding body 105 slightly change (automatic dust adjustment function: meaning of no dust adjustment).
[0049]
Next, although not shown in particular, the invention of the method for attaching the receiving bracket 4 of the first embodiment to the door frame 3 will be described.
[0050]
